HyperDex 0.2b8

[Robert Escriva]

Last night I pushed new tarballs and Debian/Ubuntu/Fedora packages for
HyperDex 0.2b8. The most user-visible changes include:

- More-human command-line interfaces to the coordinator and daemon
- A control program for connecting to the HyperDex coordinator (no more
netcat)
- Improved support for types. Scripting languages automatically
marshall and demarshall integers when a field is declared as an
integer
- Atomic operations. Support for a conditional put (like a CAS), or an
atomic increment/decrement (like a lock xadd)

Behind the scenes, we've got a handful of bug fixes, and some test cases
which demonstrate that HyperDex will not exhibit inconsistencies (even
in the presence of failures).

All users are encouraged to upgrade and help us test out this new
release.
